DEVICE FOR OlLING THE ARBORS OF SHELL-=ROLLERS.

SPECIFICATION forming part of Letters'Patent No, 313,133, dated March 3,1885.

Application filed January 15, 1885.

To aZZ whom it may concern:

Be it known that we, CHARLES S. TUTTLE and FRANKLIN TWITOHELL, citizensof the United States, residing at Nashua, in the county of Hillsboroughand State of New Hampshire, have invented certain new and usefulImprovements in Devices for Oiling the Arbors of ShellRollers, of whichthe following is a specification, reference being had to theaccompanying drawings.

Our invention relates to spinning mechanism, and has for its purpose toprovide novel devices for oiling the arbors of shell-rollers,railway-head's, and drawingframes, whereby the consumption oflubricating-oil is largely diminished, the bearings are properly andevenly supplied, the distribution is proportioned to the speed of theroll, and the necessity of frequent oiling is avoided.

The invention consists in the several novel features of construction andcombinations of parts hereinafter fully described, and finally pointedout in the claims annexed to this specification.

Referring to the drawings forming part of this application, Figure l isa vertical transverse section of a spinning-frame containingdrawing-rolls. Fig. 2 is a vertical axial section of the arbor with theshell rolls mounted thereon. Fig. 3 is a plan View of the arbor shown inFig. 2, one of the shell-rollers being mounted in place thereupon andthe other removed.

In the said drawingsthe reference-letter A indicates the lower steelrolls, to which rotation is imparted, and which are of any wellknown andsuitable construction. Upon these rolls rest in the usual form ofarrangement the upper rolls, B, C, and D, whereof the two latter areconnected by the saddle E, having near one end a concave seat, whichlies upon the arbor F or the neck of the shaft carrying the rolls. Alongitudinal channel or slot, 6, is out in the back of the saddle,terminating at each extremity in an aperture, 6, which opens into theconcave seat lying upon the shaft.

The letter G denotes the arbor carrying the she1l-rollers B. It is madeof steel, and is drilled from end to end, forming an axial chamber, f,which is of diminished-diameter at the central portion, as shown in Fig.2. At this (No model.)

point is formed an aperture, f, which communicates with both parts ofthe chamber f. Upon each side of this central opening, at a suitabledistance therefrom, is formed a collar, f, which is received by a recessin the end of the shell-roller, and by which lateral displacement in onedirection is avoided, and the oil prevented from flowing out upon thesurface of the arbor. Between these collars and the extremities of thearbor the latter is slightly increased in diameter, this dimension beinggreatest at or about at the central portions of those bearing surfacesupon which the shell-rolls rest. From these points the diameterdecreases very slightly in both directions. Y

Between the collars f and the ends of the arbor are formed openin gs flying in substantially the samelougitudinal line as the central opening,f, and in the periphery of the arbor are formed slots or channels/ uponeach side of and communicating with the aperturef Each of these slots isin the form of a notch cut longitudinallyin, but not througl1,the wallof the arbor, and having its bottom inclined downward from eachextremity toward the opening f. Not far from the ends of the channel fare formed two, four,or more openings,f of small diameter,andcommunicating with the chamberf.

Upon the arbor G rests a front saddle, I, having near one end a nipple,t, which penetrates the aperturcf and sits upon the arbor around it. Aperforation, '6, is out through the saddle and the nipple, therebygiving communication with the chamberf. The saddle I is suitablycurved,and its other end rests upon the saddle E at or near its centralpart. A weight, \V, is hung upon the notched back of the saddle I in theordinary manner.

The axial chamber f is in use filled with any suitable fibrous packing,and its ends are closed by plugs f. Oil is supplied through the centralopening, f, in suitable quantities, and is drawn by the rotation of theshell-roller through the openings f in the arbor, giving perfectlubrication to the bearing-surfaces. The revolution of the shellrollernaturally tends to carry the oil to the A thicken and become foul.

taining the packing. As this supply is constant in quantity,thelubrication will be equal at all times, and as the oil will be drawn outin quantities proportioned to the speed of the shell-roll, thelubrication will always be proportioned to the necessities of the case.Moreover, as the oil is all carried up and returned to thepacking-chamber, save the slight film between the bearing-surfaces, itwill readily be seen that the surplus is neither wasted nor exposed tothe atmosphere, whereby it will We not only thereby eft'ect a very greateconomy in the consumption of oil, but save the time and attenwhichvirtually divides the oil-chamber into two parts. The object of thisconstruction is to prevent the oil from flowing into one end of thearbor should the latter be inclined, and leaving the other end dry.

' Having thus fully described our invention, what we claim as new, anddesire to secure by Letters Patent of the United States, is-

1. In a spinning-frame or other mechanism, an arbor for a shell-roller,having the diameter of its bearing portion increased from each endtoward an intermediate point,where it may be greatest, and provided withan aperture at or near such point, and with longitudinallydownwardly-inclined channels opening into said aperture, an axialchamber being formed communicating with said aperture,- and with smallperforations cut at a suitable distance upon each side of the latter,substantially as described.

2. In a spinning-frame or other mechanism, an arbor for ashell-rollerhaving an axial chamber, a central aperture opening into it, collarsupon each side of said aperture, bearing portions between said collarsand the ends of the arbor, each having a tapered or diminished diameterfrom a point at or near the center toward each end, apertures formed ineach bearing portion at or near such point of greatest diameter,longitudinal channels downwardly inclined toward and opening into saidapertures, and small oil-openings upon each side of said apertures,substantially as de scribed.

3. In a spinning-frame or other mechanism the combination, with an arborhaving a central packing-chamber filled with suitable fibrous packing,of shell-rollers mounted upon said arbor near its ends, which aretapered in two directions, and a saddle having a perforated nippleseated in acentralaperture which enters the packing-chamber, said arborbeing provided at or near its points of greatest diameter withalongitudinal channel downwardly inclined from each end toward itscenter, and opening into an aperture which enters the packing-chamber,oil-openings being formed at a suitable distance upon each side of suchaperture, substantially as described.

4. In a spinning-frame or other mechanism, the combination, with thearbor G, having the collarsf the doubly-tapered bearing portionsprovided with channels f and aperturesf, ofa packing contained in acentral chamber, f, the shell-rolls B, the saddle I, having a perforatednipple, i, seated in an aperture, f, in the arbor, and the saddle E,upon which its other end rests, oil-openingsf being formed in the arbor,substantially as de- 1 at the central portion, and a feed-opening.

located in the center of the contracted part, substantially asspecified.

In testimony whereofwe aflix our signatures in presence of twowitnesses.
